Melody, if you look close at that photo of mine there's a bolt with a washer and nut then the brackets go on the bolt, then another washer and a Nylock nut. Makes it easier to install with the bolt being in place. If you look at the photo I posted at 10:16 am today, the left brace bracket from the front of the battery box is in that photo, that should give you some idea of how it mounts to the side frame.
